APPARATUS FOR INTES'I'INAL IRRIGATIONS Fernand Francois Dominique Suarez dc Mendoza.

. Paris, France Applicatio 11 Claims.

The present invention has for its object an apparatus for intestinal irrigations.

This apparatus is characterized by a reservoir placed under pressure and a reservoir placed un- 5 der vacuum, these reservoirs being interconnected by two distinct conduits constituting a closed circult traversing, at one pa t, in one oi the conduits an air compressor and an air reservoir regulating the pressure, and, at the other part, 10 in the other conduit a distributing three way cock and a suction vessel for surveyance of the substances, an equilibrium of pressure being established in all points of the circuit and the three way cock permitting of putting the rectal probe 15 in communication, under a certain constant pressure or under a certain constant degree of vacuum, either with the reservoir under pressure or with the reservoir under vacuum, so as to irrigate the intestine and to aspire, as often as neces- 20 sary the injected liquid serving as vehicle for the contents of the intestine.

Another characteristic of the apparatus resides in, the provision of a device placed ahead of the three'way cock in the conduit leading to the rectal 5 probe and permitting of leading of a medicamental solution or of a vaccine-matter into the intestine.

Difierent other characteristicswill be better understood in the course of the following de- 3 scription and by referring to the accompanying drawings which show:

. and v Fig. 7 a view of the apparatuses grouped to- 45 gether.

The general installation comprises in the first place two receptacles GI and 82 of a capacity of about eighteen to twenty litres each.

The two receptacles should be provided with 50 tight lids or covers.

The receptacle 6| could, without inconvenience, be of glass or metal, but the receptacle 62 should preferably be of glass to render visible the movements of the liquid which it contains.

55 The cover Shot the receptacle 62 is always 11 November '21, 1934,-Serial No. 754,159 In France November 21, 1933 g made of metal and is secured by appropriate means which bear strongly on the edge of the receptacle with an intermediate air-tight joiht.

The installation also comprises a pump 63 driven by an electric motor. This pump is con- 5 nected by a tube 64 to the receptacle 6|, on the one hand, and on the other hand by a tube 65 to a reservoir or tampon bottle 66..

The purpose of the pump is to create a vacuum of about 35 centimetres of mercury in the receptacle 6|, whilst it should keep up a constant pressure in the receptacle 62. The regulation of this pressure is obtained by means of the tampon bottle which is provided with an adlustable control valve 68 flxing'and maintain- 15 ing the pressure at any desired value between 1 meter 50 centimeters and 3 meters.

The receptacle 6!, or vacuum receptacle, is provided with a drain pipe I0 having a cock H. This cock comprises one plug only, provided with two distinct channels 1 and 1h. (Fig. 6). The body of the cock is connected by two ways "a and lid to the pipe 10 and by two other ways I is and TI: to an air pipe I2 traversing the cover GI and ending there.

The plug of the cock II is acted upon by a pedal ll; (Fig. 1) and is provided with a tail H1. acting, after a certain stroke, upon a pusher cook or the like 15a fitted inthe conduit 15 traversing the cover Sin and admitting water under 30 pressure into the receptacle 6|.

The plug of the cock .1! is automatically brought back and on being acted upon with aid of the pedal l1; causes the following action in chronological order: 1, the opening of the conduit I2 admitting air into the receptacle BI, and 2. the opening of the emptying conduit 10, and finally 3. the opening of the cook 15... admitting washing water into the receptacle SI.

On letting loose the pedal 1!; the same returns 40 into its starting position after having closed the, three ways in an order. inverse to the one on opening.

To control the emptying of the receptacle 6 I, an

electric indicating device is attached to said receptacle. This device can be one with a swimmer I3 controlling through the medium of a rigid rod I39. a tight interrupter 13b destined to close the circuit of a test lamp I4.

A level controlling gauge 15 is disposed on the coverlila to indicate constantly the level of liquid in the receptacle. 0 I

On the other hand a regulator 11 keeps the degree of vacuumof the receptacle 6| constantly .150 35 centimeters of mercury.

The tube I8 is led into the cover 8|- andconveys into the receptacle the liquid which has been usedfor the treatment and which holds in suspension the materials which have been evacuated 5 from the intestine.

A- tube 18 extends into the receptacle 82 and is carried by the cover 62.. To this tube is connected the piping l4 comprising a serpentine l4- and connected to the distributing elements.

0n the. other hand, the cover 82- is traversed by a sliding thermometer 80 permitting the temperature to be noted, of the liquid introduced into the receptacle 62, by an orifice 8| having a hermetic mouthpiece.

Finally on the cover is mounted a valve 82, me-

chanical or preferably mercury, of which the glass float 83 is of a form which will permit manipulation of the cover without the 'possibility, of reversing the mercury. This valve puts the receptacle 62 into communication with the atmosphere as soon as the liquid descends below a determined limit in the receptacle.

The pipe I4 is connected to one of the nozzles viz. to the nozzle 84. (Fig. 2) 01' a cock 84 with four perpendicular ways. The nozzles 84.; and 84d are inflected so as to join two vertical bottles 84. and 84:. These bottles are obturated at their upper pert and communicate with each other by a pipe 8 O The plug of the cock 84 is provided with three conduits 84;, 84a and 841 and can hence occupy three -positions controllable outwardly by an index or by any other suitable means.

In the first position (intermediate position) the conduit 841 establishes the communication be-.

tween the ways 84a and 84b. In the extreme left position the conduit 84; connects the ways 84: and 84c, and the conduit 84s the ways 84d and 841, with each other. Finally in the extreme right position the conduit 84; connects the ways 84 and 84b, and the conduit 84). the ways 84. and 84a with each other.

Into the nozzle 84 of the cook 84 is screwed the end In of a three way cock I 2, this end being provided with a screw neck 45. comprising an internal screw thread in which screws the glass receptacle 45.

In the screw neck 45' are formed two passages 45 and 45 opening into the receptacle. The passage 451, is surmounted by a tube '46 extending up into the receptacle.

This arrangement permits the flow of the liquid controlled by the cock I2 to be watched To the branch 82b of the cock is fixed the tube I| leading to the receptacle under vacuum 6|. The nozzle '20 receives a tube l5 carrying the rectal probe 1.

The plug 2a of the cock I2 is provided with a conduit |2'= permitting the interconnection, either of the tubes l4 and I5 or of the tubes l5 and H or, finally, of the tubes l4 and N (Fig. 1). T

To enable the operator to place the-plug I24 in the desired position the handle 86 controlling the said plug is provided with an index 85a moving over a dial 86 carrying marks correspond- 0 ing to the three possible positions of the plug of the cock.

To maintain the cock in these positions and to facilitate finding these positions, the cock plug has six recesses in which can lodge a ball 81 The tube H leads to the inspection vesse com- (Fig. 3), pushedby a spring 88, and adapted prising a base 28 (Fig. 4) carrying a glass hood ID.

This hood is held on the base 28' by means of a closing ring 25 tightened by wing nuts 88' mounted on' swinging screws 28'.

Joints 88 and 88 are intercalated between the base and the hood to assure the air-tightness of this latter.

The base 28' forms, at its centre, a cup pierced with a hole from which leads the tube l8. A cock I9 is mounted on this tube l8 and permits of starting or stopping the circulation of the liquid in this latter.

The base 23' is also traversed by three tubes: a tube 8| connected directly to the tube II, a tube 82 connected to the tube l8, below the cock I8 and a tube 83 connected directly to the top of the receptacle 6|.

The tube 8| is raised sufliciently high in the hood and terminates in a bent over portion, to

.divert the liquid of the column II to the centre of the hood.

The tube 82 does not extend so high and is curved back on itself to a point near the base 23' in order to form a siphon.

The tube 88 allows of an equilibrium of the vacuum between the receptacle 6| and the hood I0 to be obtained.

At the centre of the hood, above its central cup may be disposed the funnel filter 28, pierced with holes and permitting of withdrawal of some quantities of the solid materials contained in the liquid.

The base has two manometers 84 one for the control of the suction and the other for the control of the compression.

The above described apparatus functions as follows: f

The operator moves the tour way cock 84 and the three way cock l2 so that they form a communication between the receptacle 62 and the a probe 1 by the intermediary of the tubes l4 and speed twice and a half greater than the speed,

at which it is introduced. The operator can allow the liquid arriving by the tube II and the column 8| to run directly into the cup 01 the base 28' and into the pipe |8, but it it interests him he can close the cock I8 and allow the liquid to rise in the recuperating vase l0. He can then exactly survey the aspect of the liquid evacuated and, at the same time, control the volume of this liquid which should beat least equal to thevolume injected.

This method avoidsstagnation oi the liquidv in the intestine treated.

The operator could likewise inject a vaccine or a medicamental solution by placing either the one or the other inf the ampulla 84:. By closing the plug of the "k' 84 into its right position (Fig. 2), the operator diverts the current of liquid under pressure arriving through the pipe l4 and conduit 84; towards the ampulla 84 of which the air is driven out and exerts a pressure right.

60 article of furniture as (Fig. 7)..

on the solution contained in'the ampulla flr. This solution is then forced across the conduit up towards the three way cock I! and therefrom to the probe 1. An obturating system, such as 5 a float 84' can be provided for preventing the passage of the propelling liquid into the ampulla 841 when empty. Y v

, If the operator desires to'continue the injection he replaces the cock 84 to its position to the -,For emptying the ampulla propelling water, the operator can put this ampulla after operation into communication with the three way cock l2- across theconduit 8%, viz. by turning the plug of. the-cock 84 to the left, and so admit. suction water to the suction receptacle 6|. i

The operator could moreover dispose in the a certain quantity of solid material for examination or analysis.

The vase l0 should be ofsuiiicient size to contain the quantity of liquid-injected at each o'peration.

If, by inadvertence, the cock [9 being closed, the liquid rises in the vase: l0 above the summit of the tube 92, siphonage will occur ln this latter and the liquid will travel by this tube directly into the tube, l8 behind the cock l9. rrhie prevents all passage of liquid into the tube 93..

The operator can, after having finished the treatment, proceed to clean the tubing and-the vase II), for which purpo'se he moves the cock- I! so as to place in commimication the tube It with the tube ll.

The vase 6| which will have received the whole of the liquid evacuated and measured by means of thegauge 16, can be cleaned after emptying 40 by means of water under pressure coming from the pipe 15. i All accident is also rendered impossible in connection with the compression. The-regulator 68 allowsany desired constant pressure to be maintained .in the bottle 66.

.45 The temperature of. the liquid introduced into the receptacle6'2 is ve'riiled by means of the ther mometer 80. v 1

The float 63 preventscompression in the receptacle 62 when the. level of theliquid reaches an extreme no injection of air into the intestine undergoing treatment can therefore ocu v From the time that the receptacle! starts to 5 receive the liquid, the signal lamp I4 lights'and shows that the apparatus is functioning normally and that the c ck" s properly closed.

The whole of the apparatus described above can advantageously be placed in asingle portable For this purpose one could arrange the pump a in the base of the article and above the bottle regulating the pressure 66 and the receptacle 6|; Doors!!- and' 95s whenfolded down allow of 5-.seeing reaching the 'variousinspection and controlorgans placed in the article, and also form flaps which'are very'useful'to the .operator.

. Exteriorly, the article supports at its upper part, the receptacle 6! preferably-of. glass and' the re-. cuperatin'g' vase Ill mounted on a hollow column 96 adapted to'i'eceive the various supple pipes leading to the three way cock. This column 96 projects from the article in such manner as to place as close as-possible to the operator the re- 7 5 cuperating vase and to'brin'g also. the three way an. ali n} with the vase Hi the recuperating filter 20 and thus gather Huid supply reservoir,

cock within the reach ofthe operator's hand above the operation table.

It is obvious that thepump 63 could be replaced by'any other apparatus capable of creatinga pressure and a depression simultaneous y in the two circuits oi the apparatus described.

For example one could use for this purpose compressed gas cylinders or the compressed air a double flow probe without changing the position of said cock.
